IMPROVEMENT IN PLOWS.

Specification forming part of Letters-Patent No. 194,891, datedSeptember 4, 1877 application filed March 6, 1877.

To all whom it may concern.-

Be it known that we, JOHN R. CALDWELL and JAMES W. HERREN, both ofDadeville, in the county of Tallapoosa and State of Alabama, haveinvented certain new and useful Improvements in Flows; and we do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification, and inwhich- Figures 1 and 2 are side elevations, showing opposite sides. Fig.3 is a perspective view. Fig. 4 is a rear elevation, and Fig. 5 is aperspective view of the share.

Similar letters of reference indicate corresponding parts in all thefigures.

Our invention relates to certain improve ments in the frames of plows orcultivators; and it consists in the construction and combination ofparts forming the frame, substantially as hereinafter more fullydescribed, and pointed out in the claim.

In the drawing, A is the tongue or beam, the rear end of which is curvedand perforated to admit of the insertion of a bolt, a. B B is a piece ofiron, consisting of a straight arm, 13, and curved arm B, united attheir lower end, so as ,to form the slotted shoe b. The straight arm Bhas two series of holes, 0 d, one above the other, but each set orseries of perforations forming an are having the bolt 6, on which thepiece B B swings, forits center. 0 O are the handles, which are pivotedto the beam A at f, and adjustablein their relation to said beam and tothe shoe-piece B B by means of the downward-projecting converging arms DD, the lower ends of which are perforated, so that by means of a boltand nut, g, they may be adjusted in any of the upper set of perforationsc in the straight arm B of the shoe-piece. Similarly, by swinging theshoe-piece B B on its pivot e, the bolt on may be inserted in any one ofthe holes of the lower set of segmentally-arranged perforations (1, soas to secure the shoe in any given angle or position.

The upper face of the slotted shoe b has a series of notches, h, as willbe seen by reference to Fig. 3. Into these fit the flange or catch i ofthe share E, which is further kept in place by a screw-bolt, is, affixedupon its under side, (see Fig. 5,) and projecting down through the slotin the shoe 1) and nut It. By loosening the nut the share may be movedup or down on the shoe from notch to notch, and secured in any givenposition simply by tightening nut it, while by removing this nutaltogether the share may be removed and a share or blade of a differentshape substituted without in the least disarranging the other elementsof the plow.

From the foregoing description the operation of our improved plow orcultivator frame will be readily understood.

By withdrawing bolts a and g, the shoepiece B B may be swung upon itspivots until the proper pitch has been attained, when it is firmlysecured in its position by re-inserting the bolts in the correspondingholes and affixing the nuts.

The depth of furrow may be regulated by adjusting the share E uponshoe 1) in the manner described, shares of different kinds and shapesbeing affixed upon the shoe according to the character of the work to bedone.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States- The combination of the curved beamA, pivoted and adjustable shoepiece B B b, pivoted handles (J, andbraces D, adjustable upon the shoe-piece B, all arranged and operatingsubstantially in the manner and for the purpose herein shown andspecified.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in presence of two witnesses.
